Abstract

Literature review shows that rainwater is a good source of water for domestic use and has been used significantly in many countries. However, the case of Ho Chi Minh City shows that using rainwater is limited even though this city has a high volume of rainfall. By conducting a questionnaire survey with the city's inhabitants and studying related documents, this paper tries to find out the reasons that hinder the use of rainwater from the inhabitants’ perspective. Based on the paper's findings, the actions and solutions towards increasing the use of rainwater for domestic purposes are recommended, mainly for the city's inhabitants.
